FRAME FOR RAILROAD VEHICLES.

Application filed February 15, 1928. Serial No. 254,369.

of simple and strong construction; comparatively low cost of; manufacture, and ready adaptability in connection with the bodies of railro'advehicles, of various types known in present standard practice.

The improvement claimed is hereinafter fully'set forth.

In the accompanying drawing: Figure 1 is an isometrical view of a tender frame, il-' lustrating an embodiment'of the invention;

"descriptively to the specific embodiment thereof which is herein exemplified, and, first, to Figs. 1, 2 and 3, there is provided a fabricated frame structure, herein illus trated as adapted for application in a locomotive tender of present standard practice. The frame comprises two counterpart side frame members, 1, 1, each having formed integral therewith, a plurality oflaterally projecting cross tie'sections, 1, said cross tie sections on each of the two side frame members being connected by inner longitudinal members, 1 which, in the completed frame structure, abut, and are connected, in pairs, in the middle vertical longitudinal plane thereof. The side members and cross tie sections, are herein shown as of channel section, but such specific section is not of the essence of the invention, and any other preferred one may be adopted.

The ends of the cross tie sections, 1, of each side member, further from said member, except those at the front and rear ends of the frame structure, are connected, one to the other, by the integral inner longitudinal frame members, 1 which extend, parallel with the side members, at such distance therefrom as to present plane faces,

which, as before stated, are in line with the faces of the cross tie sections, and are, therefore, similarly to said sections, adapted to abut, and be connected, in the middle vertical longitudinal plane of the completed frame structure. The two side members, with their integral associated parts, are

rigidly secured together, by bolts, 2, passing through the inner longitudinal members, 1 or by other means, as riveting or'welding, if preferred.

The cross tie sections at the front and rear ends of the frame structure are connected with the sections next adjacent to them, by integral draft gear sills, 1 which extend parallel with the side members, 1, and

nearer to the longitudinal center line than the side members. Spaces are thereby left between the sills, 1*, which serve for the reception of draft and buffing gear elements.

The application of the invention, in connection with a water bottom tender, is shown in Figs. 4 ahd 5.- The construction accords, in all substantial particulars, with that shown in Figs. 1, 2 and 3, and hereinbefore described, difiering therefrom only in the provision of integral bottom plates, 1, which close the lower sides of the spaces between the side members and the cross tie sections. Said spaces are open at their tops, as shown in Fig. 5, and communicate, through their open tops, with the tender tank, the capacity of. which is thereby correspondingly increased.

The invention claimed as new and desired to be secured by Letters Patent is:

1. In a fabricated railroad vehicle frame "structure, the combination of two counterpart castings, each comprising, in an integral piece, throughout its entire length, a longitudinally extending side member, a plurality of cross tie sections, projecting laterally therefrom, inner longitudinal members connecting the crosstie sections, said inner longitudinal members abutting against counterpart members on the other casting; and means by which the abutting inner longitudinal members. are rigidly secured together.

2. In a fabricated railroad vehicle frame structure, the combination of two counterpart. castings, each comprising, in an integral piece, a longitudinally extending side member, a plurality of cross-tie sections projecting laterally therefrom, inner longitudinal members connecting the cross tie secing the end cross tie sections with the adjacent cross tie sections, said draft gear sill sections being more closely adjacent to the inner longitudinal member than the side member, said inner longitudinal members abutting against counterpart members on the other casting; and means by which the abutting inner longitudinal members are rigidly secured together.

3. A railroad vehicle frame casting, comprising, in an'integral piece, throughout its entire length, a longitudinally extending side member, a plurality of cross tie'sections, projecting laterally therefrom, and inner longitudinal members connecting the cross tie sections, said inner longitudinal members being adapted to abut against counterpartmembers on another frame cast- 20 ALFRED W.
